Operations
A model of this concept must provide:
Kernel::FT	operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r, const Kernel::Point_3 &s) const
	returns an approximation of the signed dihedral angle in the tetrahedron pqrs of edge pq.

Kernel::FT Kernel::ComputeApproximateDihedralAngle_3::operator()	(	const Kernel::Point_3 &	p,
		const Kernel::Point_3 &	q,
		const Kernel::Point_3 &	r,
		const Kernel::Point_3 &	s
	)		const

returns an approximation of the signed dihedral angle in the tetrahedron pqrs of edge pq.

The sign is negative if orientation(p,q,r,s) is CGAL::NEGATIVE and positive otherwise. The angle is given in degrees.

Precondition

p,q,r and p,q,s are not collinear.
